Which best describes the role of restriction enzymes in the analysis of eDNA?
cutting large DNA molecules into smaller pieces.
What are chromosomes made of?
They ARE specific coding sequences of 2'-Deoxy-Ribonucleic-Acid. Sweet Searching!
Is electrophoresis part of biotechnology?
Electrophoresis is used to separate molecules based on size and charge. Since biotechnology depends on knowing what you are working with, electrophoresis of proteins, DNA and RNA is a tool used by biotechnologists.
Heredity traits are transmitted from generation to generation by means of?
ANSWER: It is an attribute of phenotype not a genotype.
What is the use of spectrophotometer in biotechnology?
molecular biologists routinly work with DNA,RNA, and have devised some sample fast spectrophotometrc assays for this molecules
What is the function of a vector in biotechnology?
In Biotechnology, vectors are used to transport and insert specific DNA sequences into target genomes.
What do biotechnologists use to DNA molecules at specific sequences?
Restriction endonucleases or enzymes
What do bio technologists use to cut DNA molecules at specific sequences?
Restriction enzymes.
Where are the protein-synthesizing instructions stores on DNA molecules?
Certain sequences of nucleotides code for the production of specific proteins.
What do biotechnologist used to cut DNA molecules at specific sequences?
Restriction endonucleases or enzymes
The restriction enzyme used in constructing hybrid molecules of certain gene sequences and plasmid DNA acts by?
opening DNA molecules at specific sites,leaving sticky ends exposed. find me on kik one1992
Where in the promoter do transcription factors bind?
Completely Specific Transcription Factors bind to equally specific Dna Sequences that are located and found within The Promoter [Dna] Sequence. Up-Stream from the promoter sequence are the enhancer sequences; Down-Stream is the Operator Sequence - followed by the encoded information.
Are protein molecules made up of strands of DNA joined together by amino acid sequences?
No, protein molecules are not made up of strands of DNA joined together. DNA contains the genetic information that codes for the synthesis of proteins. Proteins are made up of amino acids joined together in a specific sequence dictated by the instructions encoded in the DNA molecule.
What does a geneticist use to cut DNA at specific base sequences?
Restriction enzymes, also known as restriction endonucleases, are used to cut DNA into smaller fragments. Restriction enzymes are found in bacteria, where they act like molecular scissors by cutting up DNA from invading viruses or bacteriophages. Each restriction enzyme recognizes a specific nucleotide sequence and cuts the DNA at that site. This process makes restriction enzymes extremely useful in biotechnology where they are used in procedures such as DNA cloning, DNA fingerprinting, and genetic engineering. There are hundreds of known restriction enzymes, and each one was named for the bacteria from which it was isolated. For example, EcoRI was isolated from Escherichia coli and HaeIII from Haemophilus aegyptius.
DNA contains instructions for making the different molecules such as proteins that a cell needs to grow and function. To use these instructions the DNA must first be into .?
Certain sequences of nucleotides code for the production of specific proteins.
DNA replications begins in areas of DNA molecules called?
replications origins, which are highly conserved DNA sequences that are recognized by the replication machinery.
True or false After replication the nucleotide sequences in both DNA molecules are identical to each other and to the original DNA molecule?
No
